Description

Technical Field

[0001] The present invention relates to the technical field related to furniture, and in particular to a bidirectional rhythmic movement and rhythmic furniture. Background Art

[0002] Motion-activated furniture, such as the motion chair, is gaining market attention as an innovative home product. By guiding the body through passive movements, the motion chair achieves physical exercise, not only aiding digestion but also accelerating blood circulation, thereby improving the health of internal organs.

[0003] In the related art, patent number CN202222068699.8 discloses a rhythm machine. However, the above-mentioned rhythm machine can only achieve rhythm in a single direction of up and down or front and back, and cannot well meet people's needs for rhythm in different directions.

[0004] Even though some patents disclose a single rhythmic chair that can move up and down and forward and backward, such as the patent number CN202121681547.4 that discloses a dual-rhythmic rocking chair base, this design has exposed some problems in actual applications. Specifically, in this design, the front and rear drive motors are responsible for driving the front and rear drive frames to move, while the up and down motion motors are installed on the front and rear drive frames. On this basis, an up and down motion frame is installed on the front and rear drive frames, which are driven by the up and down motion motors to achieve movement in the up and down directions. However, when the front and rear drive motors vibrate at high frequency to drive the front and rear drive frames, the up and down motion motors connected thereto also have to follow with high-frequency vibrations. The above design causes the up and down motion motors to be very easy to be damaged, and due to the problem of assembly clearance, noise will also be generated. Summary of the Invention

DETAILED DESCRIPTION

[0042] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0043] The following combination Figures 1-14 The present invention describes a bidirectional rhythmic movement and rhythmic furniture. The rhythmic furniture includes a massage body that supports the user and a rhythmic movement located at the bottom of the massage body. It should be noted that in some embodiments of the present invention, the rhythmic furniture is a rhythmic chair, and the rhythmic movement is located at the bottom of the chair. Of course, in some embodiments, the rhythmic movement can also be applied to furniture such as rhythmic sofas and rhythmic beds.

[0044] It is understandable that, referring to Figure 1 、 Figure 2 and Figure 3 The present invention provides a bidirectional rhythmic movement, comprising a bottom fixed frame 11, an upper movable frame 22, a bidirectional motion connector 33, the above-mentioned driving actuator, the above-mentioned driving power mechanism and a front-and-rear driving mechanism 66, the upper movable frame 22 is movably arranged above the bottom fixed frame 11, the bidirectional motion connector 33 is arranged between the bottom fixed frame 11 and the upper movable frame 22, the bidirectional motion connector 33 is used to flip and limit the upper movable frame 22 to move in the up and down, front and back directions, the up and down driving actuator 55 is arranged on the bottom fixed frame 11, the up and down driving actuator 55 is transmission connected with the upper movable frame 22, the up and down driving actuator 55 is used to lift and drive the upper movable frame 22 to move up and down; the up and down driving power mechanism 44 is arranged on the bottom fixed frame 11, the power output end of the up and down driving power mechanism 44 is transmission connected with the up and down driving actuator 55, the front and rear driving mechanism 66 is arranged on the bottom fixed frame 11, the power output end of the front and rear driving mechanism 66 is transmission connected with the upper movable frame 22, and the front and rear driving mechanism 66 is used to drive the upper movable frame 22 to move back and forth.

[0045] The bidirectional rhythmic movement provided by the present invention can realize the independent up and down or forward and backward movement of the upper moving frame 22 by arranging the upper and lower driving power mechanisms 44, the upper and lower driving actuators 55, and the front and rear driving mechanisms 66 on the bottom fixed frame 11, which can avoid the problems of short life and abnormal noise caused by the movement mechanism being driven by other movement mechanisms. The rhythmic movement can choose the required direction of movement as needed, which can better meet people's needs, and has a long life and a simple structure.

[0046] In addition to the above, a bidirectional motion connector 33 is provided. The bidirectional motion connector 33 is used to limit the upper frame 22's up and down, forward and backward movement by flipping, thereby limiting and guiding the upper frame 22 and improving safety. Due to the optimized design of the connector, the risk of motor damage due to high-frequency vibration is further reduced, thereby reducing maintenance costs and repair frequency. The upper frame 22 can move up and down independently relative to the bottom frame 11, and can also move forward and backward independently. At the same time, it can also move up and down, forward and backward simultaneously, enhancing the flexibility of movement and improving the user experience. Similarly, the design of the bidirectional motion connector 33 makes the structure of the entire rhythm chair more stable and extends the service life of the product.

[0047] It is understandable that, referring to Figure 1 and Figure 2In this embodiment of the present invention, the bottom fixed frame 11 and the upper movable frame 22 are connected by a forward and backward drive mechanism 66, which enables the upper movable frame 22 to move forward and backward within a set range, thereby ensuring that the upper movable frame 22 can move precisely in the forward and backward direction within the set range. By limiting the range of movement, the upper movable frame 22 is prevented from exceeding the safety limit, thereby improving safety. Specifically, in this embodiment, the set range of movement is between 1-10 mm.

[0048] Reference Figures 1 to 3 In an embodiment of the present invention, an up-and-down driving actuator 55 is provided on the bottom fixed frame 11 for driving the upper movable frame 22 to move up and down synchronously as a whole. The upper movable frame 22 is driven to rise and fall as a whole by the up-and-down driving actuator 55 to avoid tilting of the upper movable frame 22 when uneven force is applied to different positions.

[0049] It is understandable that, referring to Figure 4 In an embodiment of the present invention, the bottom frame 11 includes a bottom frame cross bar 111, a bottom frame longitudinal bar 112 and a rubber foot 113. The bottom frame cross bar 111 and the bottom frame longitudinal bar 112 are connected end to end to form a first rectangular frame. The rubber foot 113 is used to support the bottom frame 11. The rubber foot 113 is arranged on the lower side of the first rectangular frame.

[0050] Specifically, in this embodiment, the number of rubber feet 113 is four, which are respectively arranged at the four corners of the first rectangular frame. The number of rubber feet 113 can be set as needed.

[0051] Through the above structure, the first rectangular frame provides a solid support structure for the base frame 11, increasing the overall stability; by setting the rubber feet 113 on the lower side of the first rectangular frame, the weight of the base frame 11 can be effectively and evenly distributed on the ground, reducing local pressure on the ground; the rubber feet 113 usually have a good friction coefficient, which can prevent the base frame 11 from sliding during use, ensuring safe use, and also has a certain shock-absorbing effect.

[0052] It should be noted that, in some embodiments, although the rubber feet 113 are mainly used for fixing positions, their design may also take into account the convenience of moving the device, such as wheeled rubber feet 113 or designs with pulleys.

[0053] It is understandable that, referring to Figure 5In an embodiment of the present invention, the upper movable frame 22 includes an upper frame cross bar 221, an upper frame longitudinal bar 222, an upper frame drive connecting plate 223 and an upper frame limit connecting seat 224. The upper frame cross bar 221 and the upper frame longitudinal bar 222 are connected end to end to form a second rectangular frame. The upper frame drive connecting plate 223 is arranged in the second rectangular frame. The upper frame drive connecting plate 223 is transmission-connected to the power output end of the front and rear drive mechanisms 66. The upper frame limit connecting seat 224 is arranged in the second rectangular frame. The upper frame limit connecting seat 224 is used to connect with the bidirectional motion connector 33.

[0054] With the above structure, the upper frame cross bar 221 and the upper frame longitudinal bar 222 are connected end to end to form a second rectangular frame, which provides a stable frame structure for the upper moving frame 22, ensuring stability and durability during movement; The upper frame drive connecting plate 223 is mounted on the second rectangular frame and is connected to the power output of the front-rear drive mechanism 66, ensuring that power is effectively transmitted to the upper frame 22, achieving forward and backward drive. The upper frame limiter connector 224 is mounted on the second rectangular frame and is connected to the bidirectional motion connector 33. This helps limit the range of motion of the upper frame 22 and prevents it from exceeding preset safety limits. Under the limiting action of the bidirectional motion connector 33, the upper frame 22 can only move up and down and forward and backward. This design makes the movement of the upper frame 22 smoother and quieter, improving user comfort and user experience.

[0055] Specifically, refer to Figure 6 and Figure 7 In an embodiment of the present invention, the bidirectional motion connector 33 includes a front-to-back flip body 331 and an up-and-down flip body 332. The lower end of the front-to-back flip body 331 is arranged on the bottom fixed frame 11. The front-to-back flip body 331 is arranged vertically, and the up-and-down flip body 332 is arranged horizontally. One end of the up-and-down flip body 332 is arranged at the upper end of the front-to-back flip body 331, and the other end of the up-and-down flip body 332 is arranged on the upper movable frame 22.

[0056] With the above structure, the vertical arrangement of the front-to-back flipping body 331 allows the part to flip forward and backward in the horizontal direction, thereby providing a forward-to-backward swinging motion. The horizontal arrangement of the up-down flipping body 332 enables the part to flip up and down in the vertical direction, increasing the device's movement capability within the vertical plane, increasing flexibility and range of motion. The bidirectional movement capability allows the connector to adjust its position in two dimensions, increasing its scope of application and operational flexibility. By breaking down the movement into two independent flipping bodies, front-to-back and up-down, the movement can be controlled more precisely and the complexity caused by compound motion can be reduced. The independent flipping bodies may also mean simpler maintenance and lower failure rates, and the structure is more stable.

[0057] It is understood that, in this embodiment, the bidirectional motion connector 33 has at least three configurations, as follows: Reference Figures 1 to 3 In the first embodiment, the lower end of the front-to-back flip body 331 is hinged to the bottom fixed frame 11, one end of the up-down flip body 332 is hinged to the upper end of the front-to-back flip body 331, and the other end of the up-down flip body 332 is hinged to the upper movable frame 22. The front-to-back flip body 331 and the up-down flip body 332 can be sheet-shaped or rod-shaped.

[0058] With this structure, the hinged connection allows the flip body to rotate freely at its connection point, thereby increasing the range of motion and flexibility of the connection. This design allows the connection body to move smoothly in multiple directions without being restricted by a fixed axis. It can effectively disperse the forces generated during movement, reducing stress concentration at the connection point, thereby reducing the risk of structural damage. Because the hinge can absorb and disperse shock, this connection method helps improve the durability and reliability of the entire structure, especially in situations with frequent movement or heavy loads. Hinge points are generally simpler to maintain than fixed axes or complex joints because they are easier to inspect, lubricate, and replace. They can also adapt to different working environments, such as on uneven ground or in situations requiring multiple angles of adjustment.

[0059] In the second embodiment, the front-back flip body 331 and the up-down flip body 332 are elastic parts fixedly connected to each other. The front-back flip body 331 and the up-down flip body 332 can be elastic sheets, or rods with spring sheets, or one can be an elastic sheet and the other can be an elastic rod, depending on the specific needs.

[0060] With this structure, the elastic member absorbs and disperses impact forces during movement, reducing vibration and protecting components such as the rhythmic movement, vertical drive mechanism 44, vertical drive actuator 55, and front-to-back drive mechanism 66 from damage. The elastic member returns to its original shape after being subjected to external forces, allowing the bidirectional motion connector 33 to automatically return to its initial position after movement. Similarly, utilizing the elastic member's reset function reduces the operating time and energy consumption of the vertical drive mechanism 44 and front-to-back drive mechanism 66, as the motion mechanisms do not need to participate in the entire reset process.

[0061] Of course, it should be noted that in some embodiments, the first embodiment and the second embodiment can be combined. For example, the front and rear flip body 331 and the up and down flip body 332 are not only hinged, but also elastic, which is not limited here.

[0062] Reference Figure 14 In the third embodiment, the middle portion of the bidirectional motion connector 33 is arc-shaped.

[0063] Using the above structure, it can be understood that one end of the two-way motion connector 33 is connected to the upper movable frame 22, and the other end is connected to the bottom fixed frame 11. When moving up and down, the arc-shaped structure in the middle of the two-way motion connector 3333 can change its radius in the vertical direction; when moving forward and backward, the arc-shaped structure in the middle of the two-way motion connector 33 can change its radius in the front and back directions, and the upper and lower ends of the two-way motion connector 33 are staggered.

[0064] With the above structure, when moving up and down, the radius of the middle arc-shaped structure in the vertical direction changes; when moving forward and backward, the radius of the middle arc-shaped structure in the forward and backward direction changes, so that the bidirectional motion connector 33 can move effectively in a limited space, thereby improving space utilization; it can adapt to different motion requirements, provide flexible displacement and adjustment capabilities, and the variable radius of the arc-shaped structure in the vertical direction can act as a buffer, reducing vibration and impact during movement; the change of the arc-shaped structure expands the motion range of the connector in the vertical and forward and backward directions, increases operational flexibility and functionality, and reduces maintenance costs.

[0065] It is understandable that, referring to Figures 1 to 3 as well as Figure 14 In an embodiment of the present invention, there are two up and down driving actuators 55 , which are respectively arranged on the front and rear sides of the base frame 11 , and at least one up and down driving actuator 55 is transmission-connected to the up and down driving power mechanism 44 .

[0066] With the above structure, the two upper and lower driving actuators 55 are respectively arranged on the front and rear sides of the bottom fixed frame 11, and the upper and lower driving power mechanism 44 is transmission-connected with the upper and lower driving actuators 55. The upper and lower driving power mechanism 44 can be transmission-connected with the two upper and lower driving actuators 55 respectively, or can be connected to one of the upper and lower driving actuators 55. The two upper and lower driving actuators 55 are transmission-connected with each other. The number of the upper and lower driving actuators 55 can be set as needed, and can also be 3 or 4.

[0067] It should be noted that, in this embodiment, the transmission connection between the two upper and lower driving actuators 55 is achieved through belt transmission, gear transmission, etc.

[0068] It is understandable that, referring to Figure 8 In an embodiment of the present invention, the up and down driving power mechanism 44 includes a power base plate 441, a power bearing seat 442 and a power motor 443. The power base plate 441 is fixed to the bottom fixed frame 11, the power bearing seat 442 is fixed to the power base plate 441, the power motor 443 is installed on the power bearing seat 442, and the power motor 443 is connected to the up and down driving actuator 55 in a transmission manner.

[0069] In this embodiment, the power motor 443 can be an outer rotor motor or an inner rotor motor. With the above structure, the power base plate 441 is fixed to the bottom frame 11, providing a solid support foundation for the entire upper and lower driving power mechanism 44, ensuring the stability of the mechanism; the power bearing seat 442 is fixed to the power base plate 441, providing accurate positioning for the power motor 443, ensuring the stability and accuracy of the motor during operation; the power motor 443 is connected to the upper and lower driving actuators 55, which can effectively transmit the power of the motor to the actuator to achieve efficient motion control; the installation method of the power motor 443 makes replacement and maintenance more convenient, helps to reduce downtime and maintenance costs, and is beneficial to shock absorption and noise reduction. The power base plate 441, the power bearing seat 442 and the power motor 443 are integrated together, so that the entire upper and lower driving power mechanism 44 is compact and space-saving.

[0070] It is understandable that, referring to Figures 1 to 3 as well as Figures 8 to 10 In an embodiment of the present invention, the up and down driving actuator 55 includes an actuator base 551, an actuator bearing seat 552, an actuator crankshaft 553 and an actuator transmission member 554. The actuator base 551 is fixed to the bottom fixed frame 11, the actuator bearing seat 552 is fixed to the actuator base 551, the actuator crankshaft 553 includes an actuator body 5531 and an actuator shaft body 5532 eccentrically connected to the actuator body 5531, the actuator body 5531 is rotatably arranged on the actuator bearing seat 552, the actuator body 5531 is transmission-connected to the up and down driving power mechanism 44, the actuator transmission member 554 is arranged on the actuator shaft body 5532, and the actuator transmission member 554 is transmission-connected to the upper moving frame 22.

[0071] Through the above arrangement, the execution base 551 is fixed to the bottom frame 11, providing a stable support for the entire execution mechanism, ensuring the stability of the mechanism during operation; the execution bearing seat 552 is fixed to the execution base 551, providing precise rotation positioning for the execution crankshaft 553, ensuring the accuracy and repeatability of the execution crankshaft 553 during rotation; the execution body 5531 of the execution crankshaft 553 is eccentrically connected to the execution shaft body 5532, which can realize periodic up and down movement, which is beneficial to reduce vibration and noise during movement and improve the operation quality of the mechanical equipment; the execution body 5531 can It is rotatably arranged on the actuator bearing seat 552, so that the actuator shaft 5532 can generate vertical movement during the rotation process, thereby increasing the movement range of the mechanism; the actuator transmission member 554 is arranged on the actuator shaft 5532 and is connected to the upper movable frame 22 for transmission, which can effectively convert the movement of the actuator crankshaft 553 into the up and down movement of the upper movable frame 22, thereby realizing efficient energy transmission. In addition, by replacing different actuator transmission members 554, it can adapt to different working speeds and load requirements, thereby improving the adaptability of the mechanism, having a compact design, saving space, and being suitable for installation in equipment with limited space.

[0072] Specifically, refer to Figure 9 In this embodiment, the actuator 554 is an actuator bearing.

[0073] The vertical drive mechanism 44 rotates the actuator body 5531 of the actuator crankshaft 553. This rotation drives the actuator shaft 5532, which in turn rotates the inner ring of the actuator bearing, which in turn rotates around the axis of rotation of the actuator body 5531. Ultimately, the outer ring of the actuator bearing supports the upper frame 22, allowing it to move up and down. The use of actuator bearings significantly reduces friction between moving parts, improving mechanical efficiency and reducing energy consumption.

[0074] In this embodiment, there are at least three ways of cooperation between the upper movable frame 22 and the upper and lower driving execution bearings 554, as follows; Reference Figure 3 In the first embodiment, the execution transmission member 554 is arranged in contact with the upper movable frame 22. When the upper movable frame 22 is engaged with the execution bearing, the upper movable frame 22 is supported by the execution bearing. Due to the gravity of the upper movable frame 22, the upper movable frame 22 and the upper and lower drive execution bearings 554 will maintain contact, thereby improving the reliability of the transmission.

[0075] Reference Figure 5 and Figure 14 In the second embodiment, a vertically arranged execution flip connector 555 is provided between the outer periphery of the execution transmission member 554 and the upper movable frame 22 .

[0076] Reference Figure 11In the third embodiment, a vertically arranged execution flip connector 555 is provided between the outer periphery of the execution transmission member 554 and the bidirectional motion connector 33 .

[0077] It should be noted that the execution flip connector 555 is elastic in the front-to-back direction. By using the elastic execution flip connector 555, the mechanical structure can be simplified, the number of components that require precise alignment can be reduced, and the manufacturing cost and maintenance difficulty can be reduced; it can absorb and alleviate the impact and vibration caused by movement or load changes, and protect the execution bearings and other mechanical components from damage.

[0078] In this embodiment, by always maintaining symmetrical and antagonistic motions between the two sets of actuator crankshafts 553, the driving forces of the two sets of actuator crankshafts 553 on the upper movable frame 22 in the front-to-back directions can be offset; a hinged manner can also be adopted to make the actuator flip connector 555 hingedly connected to the outer ring of the actuator bearing and the upper movable frame 22 respectively. In order to prevent the hinged upper movable frame 22 from tipping to one side under the action of gravity, the actuator bearing can be set on the upper part of the upper movable frame 22, and the upper movable frame 22 can be lifted by using the actuator flip connector 555.

[0079] In this embodiment, the up-and-down driving actuator 55 is a crank mechanism. Of course, in some embodiments, the up-and-down driving actuator 55 can also be configured as a cam mechanism.

[0080] It is understandable that, referring to Figure 12 and Figure 13 In an embodiment of the present invention, the front and rear driving mechanism 66 includes a driving base 661, a driving motor 662, a driving crankshaft 664 and a driving assembly. The driving base 661 is fixed to the bottom fixed frame 11, the driving motor 662 is fixed to the driving base 661, the driving crankshaft 664 includes a driving body 6641 and a driving shaft 6642 eccentrically connected to the driving body 6641, the driving body 6641 is rotatably provided on the driving base 661, the driving motor 662 is transmission-connected to the driving body 6641 through a coupling 663, one end of the driving assembly is connected to the driving shaft 6642, and the other end is transmission-connected to the upper movable frame 22.

[0081] With the above structure and the above setting, the driving base 661 is fixed to the bottom fixed frame 11, providing a stable support for the entire front and rear driving mechanism 66, ensuring the stability of the mechanism during operation; the driving motor 662 and the driving body 6641 of the driving crankshaft 664 are both fixed to the execution base 551, providing precise rotational positioning for the driving crankshaft 664, ensuring the accuracy and repeatability of the driving crankshaft 664 during rotation; the driving body 6641 of the driving crankshaft 664 is eccentrically connected to the driving shaft 6642, which can realize the drive component to drive the upper moving frame 22 to move forward and backward periodically, which is beneficial to reduce vibration and noise during movement, improve the operation quality of the mechanical equipment, and can effectively convert the movement of the driving crankshaft 664 into the forward and backward movement of the upper moving frame 22, realizing efficient energy transfer, compact design, space saving, and suitable for installation in space-constrained equipment.

[0082] Reference Figure 12 In the first embodiment of the present invention, the driving assembly includes a driving rocker 665 and a driving articulated seat 666. The driving rocker 665 is rotatably mounted on the driving shaft 6642. One end of the driving articulated seat 666 is hingedly connected to the driving rocker 665, and the other end is fixedly connected to the upper movable frame 22.

[0083] With the above structure, the coupling 663 and the driving crankshaft 664 are driven to rotate by the front and rear driving motors 662, and the driving crankshaft 664 is used to drive the articulated seat 666 to rotate up and down and forward and backward. Because the driving rocker 665 is rotatably connected at both ends, the driving rocker 665 can only rotate in the up and down directions, so the driving rocker 665 will not drive the upper movable frame 22 to move up and down, and finally transfer the kinetic energy in the forward and backward directions to the upper movable frame 22, driving the upper movable frame 22 to move forward and backward; the articulated connection can play a certain shock-absorbing and buffering role, reducing the damage to the entire mechanism caused by impact or vibration. By connecting the driving rocker 665 and the driving articulated seat 666, the overall structure can be simplified, unnecessary complex components can be reduced, and maintenance and replacement can be facilitated.

[0084] Of course, refer to Figure 13 In the second embodiment of the present invention, the driving assembly includes a driving sleeve 667 and an elastic rocker arm 668. The driving sleeve 667 is rotatably mounted on the driving shaft 6642. One end of the elastic rocker arm 668 is fixedly connected to the driving sleeve 667, and the other end is fixedly connected to the upper movable frame 22.

[0085] In order to reduce wear, a bearing can be set in the drive sleeve 667, and the coupling 663 and the drive crankshaft 664 are driven to rotate by the drive motor 662, and the drive sleeve 667 is driven to rotate up and down and front and back by the drive crankshaft 664. Because the elastic rocker arm 668 is elastic in the up and down directions, the elastic rocker arm 668 will not drive the upper movable frame 22 to move up and down, and finally the kinetic energy in the front and back directions is transferred to the upper movable frame 22, driving the upper movable frame 22 to move back and forth.

[0086] Working process of the present invention: During operation of a bidirectional rhythmic movement of the present invention, when the rhythmic movement needs to move up and down, the up and down driving power mechanism 44 rotates the actuator crankshaft 553, which drives the actuator shaft body 5532 to rotate. The actuator shaft body 5532 drives the inner ring of the actuator bearing to rotate, while simultaneously revolving around the rotation axis of the actuator body 5531 of the actuator crankshaft 553, and finally supports the upper movable frame 22 for up and down movement through the outer ring of the actuator bearing. During the up and down movement of the upper movable frame 22, the up and down flip body 332 flips up and down, and the left and right movement of the upper movable frame 22 is restricted by the up and down flip body 332. The front-to-back movement of the upper movable frame 22 is limited by the driving hinge seat 666 or the elastic rocker arm 668 of the front-to-back driving mechanism 66. When the rhythm movement needs to move back and forth, one implementation method is: the driving motor 662 drives the coupling 663 and the driving crankshaft 664 to rotate, and the driving crankshaft 664 drives the driving sleeve 667 to rotate in the up-down and front-to-back directions. Because the elastic rocker arm 668 is elastic in the up-down direction, the elastic rocker arm 668 will not drive the upper movable frame 22 to move up and down, and ultimately the kinetic energy in the front-to-back direction is transmitted to the upper movable frame 22, driving the upper movable frame 22 to move back and forth. Another implementation is: the front and rear drive motors 662 are used to drive the drive coupling 663 and the drive crankshaft 664 to rotate, and the drive crankshaft 664 is used to drive the articulated seat 666 to rotate up and down and forward and backward. Because the two ends of the drive rocker 665 are connected in rotation and can only rotate in the up and down directions, the drive rocker 665 will not drive the upper movable frame 22 to move up and down. The kinetic energy of the final component in the forward and backward directions is transmitted to the upper movable frame 22, driving the upper movable frame 22 to move forward and backward. During the forward and backward movement of the upper movable frame 22, the front and rear flip bodies 331 flip forward and backward, and the front and rear flip bodies 331 are used to limit the left and right movement of the upper movable frame 22.
